Patented .luly 26, 1932 UNTD STATES ERNEST L. NORBERG, OF SAN FRANCISCO,CALIFORNIA LAVATORY Application :filed March 30,1931. Serial No.526,160.

My invention relates to toilet apparatus and more particularly itrelates to a novel dental lavatory or a wash basin which is adapted toserve as a cover for the liush tank of a toilet bowl.

Heretofore, in equipping bath rooms and the like, it has been customaryto supply only one wash basin and the users of the bath room have beencompelled to use the same basin l0 for washing purposes that others usefor brushing their teeth and for gargling. Such conditions areunsanitary and unless the basin is kept immaculate at all times, thereis danger of contracting contagious diseases. In some instances aseparate throatand dental lavatory is provided, but the cost `'of suchequipment is prohibitive except in elaborate installations.

It is a general object of my invention to rovide a basin which can bedisposed over the ilush tank of a toil-et and which utilizes theoverflow pipe of the tank'as a drain.

Another obj ect is to provide a basin which is adapted to be supportedby the iiush tank of a toilet and which has a shape such that theposition of the toilet does not interfere with the use of the basin.

Another object is to provide a basin of the character described whichserves as a cover i 3D for the flush tank.

H attained in the embodiments of my invention illustrated in theaccompanying drawing, in which:

Fig. 1 is an elevational view of an installation embodying theprinciples of my invention.

Fig. 2 is a side view showing the flush tank and basin of my inventionin cross section.

Fig. 3 is a plan view of the embodiment illustrated in Figs. 1 and 2.Fig. 4c is a plan view of a modification.

In its preferred form my invention comprises a basin which is adapted tobe supported by the flush tank of a toilet and which serves as a coverfor the flush tank. An outlet is provided for the basin which utilizesthe overflow pipe of the flush tank for a drain and if desired, anoverflow conduit can be provided for the basin which also communicatesdirectly with the overflow pipe of the flush tank. If desired, the basincan be provided with a protective back whichis adapted to be secured tothe wall on which the flush tank is mounted kby means of a removablespout, which spout also serves to deliver Water to the basin. The basincan have a shape such that the forward portion of the basin is oilsetromfthe line of the toilet so that the positionoi the toilet does notinterfere in any way with the use of the basin or, if desired, theoutline of the basin can have a contour which permits easy access to thebasin from either sidev of the toilet.

lhile the basin of my invention is'particularly suitable for a dental,lavatory and thus can serve as an auxiliary Xture in conjunction ywiththe main wash basiny or' an installation, the invention is not limitedto such use. It may be desirable in close'quar ters, for example, toutilize the basin of my invention as the main'basin or as the sole basinof the installation.

Referring now to the drawing, I. have shown a toilet bowl 16 adapted tobe flushed by water supplied from a flush tank 17. lThe water in theflush tank 17 is adapted tobe replenished bythe action' of a suitableloat valve (not shown) or its equivalent, in accordance with the usualpractice for such installations.

Anoverow pipe 18 is provided for precluding` the water in the tank yfromexceeding a level which is above the upper or open end of the overflowpipe. A Hush' E valve 19 controls the flow of water from the tank 17into the toilet bowl 16 and is adapted to be operated by suitablelinkage (not shown) actuated by a handle 21'conveniently placed on ornear the Hush tank. 1When the water in the tank 17 rises to the top ofthe overiow pipe 16, due to leakagek inthe supply valve or from anyother cause, any further rise in the level of the water is prevented,since the excess water is carried away 100 through the pipe 1S and hasclearpassage through a fitting 22 into the bowllG.

Over the top of the flush tank 17 andserving as a cover therefor lprovide a basin 23. The basin E23 is preferably provided with aprotective and sanitary back Q4 and a spout 26 for delivering wat-er tothe basin under the control of the faucctsQi' and 28 preferably passesthrough the back The spout 26 is preferably made removable, as byproviding a threaded connection 29 between the spout and the deliverypipe extending from the faucets 527 and Q8. A suitable rose 3l can besecured to the spout 26 which serves to enO'aO'e the back and tlierebfirinl retain the basin on the tank 1T and against the wall 32.

A suitable outlet 33 adapted to be closed the basin andV an overflowconduit 35 can` extend between overflow ports EST in the basin to apoint near the outlet 33. The outlet from the basin communicatesdirectly with the overflow'pipe 1S and to preclude any of the contentsof the basin from discharging into the water 3S in the tank 1'?, aconduit 39 can be provided from the outlet which extends for a shortdistance into the mouth of the overflow pipe. Thus, the entire dischargeof the basin is delivered directly into the overflow pipe 1S and intothe toilet bowl 16 without in any way contaminating the water in theflush tank 17, which for sanitary reasons and to preventl clogging ofthe sys teni must be kept fairly olea f The conduit 39 extending intothe overflow pipe 18 is preferably of smaller diameter than the mouth ofthe overflow pipe so that it does not interfere with the normal functionof the overflow pipe. lf desired, the mouth of the overflow pipe can beflared outwardly, as shown, thereby permitting the use of a dischargeconduit 39 of larger diameter.

ln the embodiment of the invention illusytrated in Figs. 1 to 3, thebasin Q3 has a semi-circular shape, thereby enabling convenient accessto the basin from either side of the toilet and the position of thetoilet does not seriously interfere with standing room adjacent 'thebasin.

If desired, the basin can have a semiliexagonal or semi-octagonaloutline thereby presenting a rectilinear surface toward a personstanding Von either side of the basin. HIn the modification illustratedin Fig. 4, for example, I have shown one forinof basin having a shapesuoli that it presents a rectilinear surface toward the user. In thismodification,

'fr however, the front of the toilet bowl 1G is oli- Y set from theVfront of the basin 41. It will be noticed that the edge, 42 of the basinmakes an acute angle with a vertical plane lying perpendicular to thefront of the `toiletbowl, in-

` dicated by the dot-anddash line in Fig. Lhand thus there is nointerference with the stand-V ing room in front of the basin.

From theV foregoing theV advantages of my novel basin will be apparent.The basin can be substituted for theV basin heretofore coininonlyemployed or it can be used as an auX-V iliary dental lavatory inconjunction with the main basin ofthe installation. By employing theoverflow pipe of the flush tank as a drain," extra plumbing is avoidedand the trap 1. ln a flush tank for a toilet bowl, an overiiow pipe forprecluding` the water in the tank from exceeding a predetermined level,a cover for said flush tank, said cover being in the form of a basin, anoutlet at the bottom of the basin, said outlet communicating directlywith said overflow pipe, and said cover having an outline which presentsat least one reef tilinear edge making an acute angle with a verticalplane lying perpendicular to the front of the toilet bowl, whereby thetoilet bowl does not interfere with the use of the basin.

2. A toilet bowl, a 'flush tank disposed directly behind said toiletbowl, a cover for said flush tank, and a wash basin in said cover, saidwash basin having a front edge which makes an acute angle with thevertical plane passing through the line of centers of said toilet bowland said flush tank, whereby said toilet bowl presents no interferencewith the standing room of a user of the basin.

In testimony whereof, I have hereunto set my hand. Y
